I am happy to report that I’ve got the bike up and running. It is working fine and is fun to ride, though a very different experience compared to my wife’s Verve+. The sales information and owner’s manual show a sales date of 2011, so is something of a senior citizen as an e-bike.

The battery is just strapped to the rack for now. It is 24v and 20ah, and is thicker than the defunct original battery, which was 10ah. I wired the new battery into the original controller, and it seems to work just fine, though is probably more battery than I really need. It looks mighty big in the photo, but in reality is not much more than the original.

Thanks for the advice! Glad I didn’t give up on it.
